HiPOD: A Sedimentary Fan in Southeast Gale Crater

This image covers a fan of sedimentary rock on the southeast crater floor. Ridges on the fan surface may be composed of coarse-grained sediment deposited in ancient streams. More recent wind erosion of the surrounding finer sediments could have left these channel deposits elevated in “inverted relief.” A closeup shows some of these ridges, as well as light-toned layers of sediment.
